Problems solved by technology

[0005] The purpose of the present invention is to provide a microbial water treatment agent for heavy metal organic wastewater in view of the current high cost of treating heavy metal-containing organic wastewater and secondary pollution. The sediment produced after treatment with the microbial water treatment agent The stripping property of the substance (alum flower) is good, basically no solid particles will be released into the water, and the action speed is fast and the treatment effect is stable. Generally, there is no need to increase the adsorption time when using it

Abstract

The invention belongs to the technical field of wastewater environmental-protection treatment, and particularly relates to a microorganism water treatment agent for heavy metal organic wastewater. The microorganism water treatment agent is prepared from the following raw materials: oyster shells, potassium feldspar, olivine, talc, serpentine, chlorite, attapulgite, ammonium molybdate modified bentonite, diatomaceous earth, aluminium polychlorid, magnesium hydrate, gram-negative bacteria, Bacillus mojavensis, polyacrylamide, tartaric acid, malic acid, citric acid, chitosan, ethylene glycol diglycidyl ether, epoxy chloropropane, thiosemicarbazide cellulose, corn starch, calcium alginate, hansenula polymorpha, candida, trailing plant, fagus longipetiolata sawdust, pinus sylvestris sawdust, walnut shell, lupulus, dehalogenase, horseradish peroxidase, urease and propionibacterium pentosaceum. A precipitate (alum floc) produced after treatment with the microorganism water treatment agent has good strippability, no solid particle is released into water basically, and the microorganism water treatment agent has rapid action speed and stable treatment effect, so that the adsorption time is usually not required to be prolonged during use.

Description

technical field [0001] The invention belongs to the technical field of waste water environmental protection treatment, and in particular relates to a microbial water treatment agent for heavy metal organic waste water. Background technique [0002] In recent years, industries such as metallurgy, electroplating, tanning and catalyst preparation have produced a large amount of organic wastewater containing high concentrations of heavy metals, which will eventually be discharged into the natural water system. If these wastewaters are not treated, they will cause serious damage to human health and life. Therefore, it is urgent to develop new methods for treating such wastewaters with high efficiency and harmlessness. [0003] Organic wastewater containing heavy metals is the most common and important industrial wastewater. This kind of wastewater contains a large amount of high-concentration heavy metals and organic pollutants that are difficult to degrade, such as dyes, aniline...
